Convertible Hydrogel Injection Sequentially Regulates Diabetic Periodontitis.

Diabetes exacerbates periodontitis by overexpressing reactive oxygen species (ROS), which leads to periodontal bone resorption. Consequently, it is imperative to relieve inflammation and promote alveolar bone regeneration comprehensively for the development of diabetic periodontal treatment strategies. Furthermore, an orderly treatment to avoid interference between these two processes can achieve the optimal therapeutic effect.

Bioinspired drug-delivery system emulating the natural bone healing cascade for diabetic periodontal bone regeneration.

Diabetes mellitus (DM) aggravates periodontitis, resulting in accelerated periodontal bone resorption. Disordered glucose metabolism in DM causes reactive oxygen species (ROS) overproduction resulting in compromised bone healing, which makes diabetic periodontal bone regeneration a major challenge. Inspired by the natural bone healing cascade, a mesoporous silica nanoparticle (MSN)-incorporated PDLLA (poly(dl-lactide))-PEG-PDLLA (PPP) thermosensitive hydrogel with stepwise cargo release is designed to emulate the mesenchymal stem cell "recruitment-osteogenesis" cascade for diabetic periodontal bone regeneration.

Microbial Natural Product Alternariol 5-O-Methyl Ether Inhibits HIV-1 Integration by Blocking Nuclear Import of the Pre-Integration Complex.

While Highly Active Antiretroviral Therapy (HAART) has significantly decreased the mortality of human immunodeficiency virus (HIV)-infected patients, emerging drug resistance to approved HIV-1 integrase inhibitors highlights the need to develop new antivirals with novel mechanisms of action. In this study, we screened a library of microbial natural compounds from endophytic fungus sp. and identified alternariol 5--methyl ether (AME) as a compound that inhibits HIV-1 pre-integration steps.

Effect of Coriolus versicolor polysaccharides on the hematological and biochemical parameters and protection against Aeromonas hydrophila in allogynogenetic crucian carp (Carassius auratus gibelio).

The effect of dietary intake of Coriolus versicolor Polysaccharides (CVP) on the hematological and biochemical indices of Allogynogenetic crucian carp (Carassius auratus gibelio) was investigated. Fish were fed CVP supplemented diets (0, 0.25, 0.
